Meshtastic maintenance and repair

Hello!

I'm completing a project at uni, and we're incorporating meshtastic into our project solution. I was having trouble finding answers regarding maintenance and repair, and was wondering if you could help! thanks !

What is the maintenance of nodes/mesh networks like?

How often are maintenance checks done/do nodes need to be regularly maintained?

How would you go about repairing/replacing nodes?

Thank you !!
